Work Breakdown Structure Dictionary

The Work Breakdown Structure Dictionary is a useful resource for project management, and should be consulted for relevant information on each component of the work breakdown structure (WBS). The WBS dictionary includes entries for each WBS component that briefly defines the scope or statement of the work, defines deliverables, contains a list of associated activities, and provides a list of recognized milestones to gage progress.

The Work Breakdown Structure Dictionary is an essential information resource for project management. It should be consulted before commencing any work component in order to insure that proper standards, procedures, and quality control measures are being followed. Due to ever changing circumstances, the Work Breakdown Structure Dictionary is under constant revision. Therefore, frequent review of its contents will assure proper project management.

This term is defined in the 3rd edition of the PMBOK but not in the 4th.
